[Samba] 3.0.28 continuously dumping core

[Robert Gehr]

Hello all

Compiled 3.0.28 from source and get continuous core dumps. The machine 
running as PDC continous to work though.
Core dumps are reproduceable and happen when, for example, I am trying 
to connect to a share that does not exist as well as when I install a 
new printer driver using the Microsoft wizard thing.

We are running two other machines with 3.0.28 without any core dumps at all.

Here the dump and following what smbd is linked against.
Compiler used is: gcc-4.1.2
